A

A big bowl of milk can be a great way to start the day. Many snack bars contain nutrients that help our bodies stay strong and healthy. But some of these foods are packed with too many vitamins and minerals. According to a new study by the Environmental Working Group (EWG), this extra fortification may be more harmful than helpful.

Of the tested snack bars, 27 have more than 50% of the recommended amounts of vitamin A, niacin and zinc. Nutrition facts listed on packages are based on recommended daily values for adults, who are physically larger and require more vitamins and minerals. So when kids eat these cereals (麥片) and snack bars, they are getting more nutrients than they need.

Vitamin A, niacin (煙酸) and zinc (鋅) are best in fresh and unprocessed foods that are in their natural state. Vitamin A helps you see at night. It occurs naturally in eggs, meat and carrots. Niacin is a vitamin that helps our bodies make energy. It is found in foods like fish, seeds, and peanuts, as well as in whole grains like wheat and brown rice. Zinc helps our bodies fight off infection. It is found in many foods, including wheat-based products, meats, beans and nuts.

Children typically eat more than one serving of cereal or snack bars a day, in addition to taking vitamin supplements. Eating large amounts of these nutrients can be dangerous to kids’ health. Too much vitamin A can cause liver damage, and high levels of zinc can destroy the body’s natural immunity, or power to fight infection.

The EWG authors are calling for the FDA to make changes to its guidelines for nutrient intake and revise its daily values to match kids’ diets.

【解析】本文是議論文。文章通過對孩子飲食現(xiàn)狀的研究和調(diào)查可知，過量營養(yǎng)對孩子們有很大的壞處，專家認(rèn)為，這種情況需要得到有效的控制。

【1】 B 推理判斷題。該段介紹了研究的情況，特別是聯(lián)系第四句及最后一句So when kids eat these cereals and snack bars, they are getting more nutrients than they need，可知，孩子需要的營養(yǎng)比成年人要少，故正確答案為B。

【2】A 推理判斷題。文章第三段介紹了營養(yǎng)對健康的好處，根據(jù)其中Zinc helps our bodies fight off infection. It is found in many foods, including wheat-based products, meats, beans, and nuts可知，要避免感染需要吃富含鋅的食物，包括肉和堅(jiān)果。

【3】 C 推理判斷題。本段主要介紹了過量營養(yǎng)的壞處，這樣C項(xiàng)符合題意。根據(jù)該段第二句中的Eating large amounts of these nutrients可知，孩子們也許喜歡吃這些東西，但這不是作者想要告訴讀者的段落思想，故A項(xiàng)錯誤。

【4】 A 主旨大意題。本文主要介紹了營養(yǎng)和孩子們的健康的關(guān)系，側(cè)重于過量營養(yǎng)對健康的負(fù)面的作用，據(jù)此可以推知，A項(xiàng)為本文最佳標(biāo)題。聯(lián)系主題思想，本文不是介紹三大營養(yǎng)，所以C項(xiàng)不對。
